Assume that the voltage of the battery is 9 V and that the three resistors are identical. What is the potential difference across each resistor?

• 12 V

• 0 V

• 3 V

• 4 V

In the circuit below, what is the voltage across R1?

• 12 V

• 6 V

• 8 V

• 4 V

What is the current through R1?

• 10 A

• 5 A

• 7 A

• 2 A

The lightbulbs in the circuit below are identical with the same resistance R. Which circuit produces more light? (brightness ÜÞ power)

• circuit 1

• circuit 2

• both the same

• it depends on R

In a parallel circuit which of the following is the same value throughout the circuit?

• Voltage
• Current
• Resistance
• Charge

In a parallel circuit which of the following varies based on the amount of resistance

• Voltage
• Current
• Ohms Law
• Charge

Find the total resistance, total current and total voltage for the following circuit

• V_{T = 9 V}
  I _{T = 3}
  R_T = 14
  
• V_{T = 9}
  I _{T = 0.64}
  R_T = 14
• V_{T = 9} 
  I _{T = 6.3}
  R_T = 1.4
• V_{T = 9}
  I _{T = 0.64}
  R_T = 1.4
